public class SimpleContentWatch extends ComposingWatch
The AdjacentTextNodeMergerFeed is used when the node is constructed as a result of a computation on the streamed data,
for example xsl:value-of select="distinct-values(.//@price)". By contrast, a SimpleContentWatch
is used when the streamed nodes are selected directly, for example xsl:value-of select=".//@price".
Both a Feed and a Watch are needed because a simple content constructor operates on a sequence of nodes without simply atomizing the sequence.

| Modifier and Type | Method and Description |
|---|---|
void |
close()
The close() method is called immediately before the Watch is destroyed, that is,
when the element whose declaration scopes the constraint implemented by this
Watch goes out of scope.
|
void |
endSelectedParentNode(int locationId)
Signal that the endElement event has occurred for the element whose startElement
event caused the Watch to be activated.
|
void |
notifySelectedLeafNode(FleetingNode node,
int locationId)
Signal that a node (other than an element) that matches the selection
has been found.
|
Receiver |
startSelectedParentNode(FleetingNode node,
int locationId)
Signal that an element has been found that matches the selection that this
Watch is looking for.
